Ultimate Expedition - All Episodes

Dateline NBC presents in-depth coverage of news stories. Rather than just reading news reports, as most news shows do, the reporters for this show research their subjects and interview the people closely involved to create an informative work of investigative journalism.

Tom Gleeson stars as the Taskmaster, with Tom Cashman his devoted assistant. Each week the two Toms set five comedians a range of ridiculous tasks designed to bamboozle brains and put funny bones to the test.

Who'll master the tasks? The cleverest clogs will score the most points from the Taskmaster, while bemusement and bafflement will be rewarded with the fewest points. At series' end, the comedian with the most points will be crowned Taskmaster champion.

The Rookie is inspired by a true story. John Nolan is the oldest rookie in the LAPD. At an age where most are at the peak of their career, Nolan cast aside his comfortable, small town life and moved to L.A. to pursue his dream of being a cop. Now, surrounded by rookies twenty years his junior, Nolan must navigate the dangerous, humorous and unpredictable world of a "young" cop, determined to make his second shot at life count.

In a ruined and toxic future, thousands live in a giant silo deep underground. After its sheriff breaks a cardinal rule and residents die mysteriously, engineer Juliette starts to uncover shocking secrets and the truth about the silo.
